Abstract

The invention relates to a method for manufacturing a packaging of the tray type, consisting of at least two cardboard layers. This method is characterised in that glue is coated on the outer surfaces (17, 19) of each cardboard layer (5, 6) on which a covering film (10, 12) is applied, in that a slow-setting glue is coated on the inner surfaces (23, 24) of the cardboard layers (5, 6), in that, after placing these inner surfaces in contact, flat portions (29, 30, 31) are cut out and shaping is then carried out, the cutting and the shaping being performed before the glue finally sets. The invention relates to the packaging industry.

Description

L'invention a trait, d'une part, à un procédé de fabrication d'un emballage du type barquette constitué d'au moins deux couches de carton, de matériaux fibreux, cellulosiques, métalliques, plastiques et, d'autre part, à un produit obtenu par l'application de ce procédé. The invention relates, on the one hand, to a method of manufacturing a packaging of the tray type consisting of at least two layers of cardboard, of fibrous, cellulosic, metallic, plastic materials and, on the other hand, to a product obtained by the application of this process.

Pour la réalisation d'emballages en carton du type barquette, on connaît déjà plusieurs procédés de fabrication. For the production of cardboard packaging of the tray type, several manufacturing processes are already known.

Un de ces procédés connus consiste à découper des plats dans une bande de carton, puis de réaliser dans ces plats des découpes supplémentaires pour définir des panneaux ainsi que des lignes de pliage et, finalement, on obtient l'emballage désiré en pliant les différents panneaux.One of these known methods consists of cutting dishes from a strip of cardboard, then making additional cuts in these dishes to define panels as well as fold lines and, finally, the desired packaging is obtained by folding the various panels. .

Toutefois, ce procédé ne peut être utilisé que pour des emballages ayant une forme parallélépipédique mais ne peut s'appliquer à des barquettes de forme ronde. De plus, lorsque la bande de carton doit être composée d'une pluralité de couches de carton pour conférer à l'emballage une certaine rigidité il s'avère que le procédé par pliage est très malaisé et pose de nombreux problèmes. However, this method can only be used for packages having a parallelepiped shape but cannot be applied to trays of round shape. In addition, when the cardboard strip must be composed of a plurality of layers of cardboard to give the packaging a certain rigidity, it turns out that the folding process is very difficult and poses many problems.

Pour pallier à ces difficultés, on a réalisé un autre procédé consistant à découper des plats dans une bande constituée de plusieurs couches de carton, puis on introduit ces plats dans une façonneuse qui, en déformant le plat, permet d'obtenir un emballage présentant la forme voulue. To overcome these difficulties, another process has been carried out consisting in cutting dishes from a strip made up of several layers of cardboard, then these dishes are introduced into a shaping machine which, by deforming the dish, makes it possible to obtain a packaging having the desired shape.

Cependant, ce dernier procédé présente de nombreux inconvénients. En effet, le matériau de base, à savoir les bandes à plusieurs couches de carton collées les unes aux autres, est réalisé par un premier fabricant. Cette bande est stockée plus ou moins longtemps sous forme de bobines ou de feuilles. Au cours de ce stockage se produit une adhérence durable des différentes couches de carton collées de sorte que l'on est en présence d'un matériau compact d'une certaine épaisseur. Ces bobines ou ces feuilles sont ensuite acheminées vers le fabricant d'emballage proprement dit. However, the latter method has many drawbacks. Indeed, the basic material, namely the strips with several layers of cardboard glued to each other, is produced by a first manufacturer. This strip is stored more or less long in the form of reels or sheets. During this storage takes place a lasting adhesion of the different layers of glued cardboard so that one is in the presence of a compact material of a certain thickness. These reels or sheets are then sent to the packaging manufacturer itself.

Ainsi, non seulement, le coût est relativement élevé en raison des frais de stockage, de manutention et de transport, mais il s'avère également qu'il est relativement difficile et lent de former des barquettes à partir de bandes à plusieurs couches de carton collées ayant subi un certain temps de stockage. En effet, il s'avère absolument nécessaire de chauffer le matériau lors du façonnage de la barquette. Il en résulte des nouveaux frais pour assurer le chauffage alors qu'en raison du temps nécessaire audit chauffage, le rendement est relativement faible.De plus, la réalisation des barquettes est rendue difficile du fait de l'immobilité des différentes couches de carton collées risquant qu'après formage l'emballage, en raison d'une certaine élasticité du matériau, a tendance à se déformer et à reprendre sa position plate initiale Cet inconvénient ne peut être annihilé qu'en procédant au chauffage du matériau lors du façonnage de la barquette. Thus, not only is the cost relatively high due to the costs of storage, handling and transport, but it also turns out that it is relatively difficult and slow to form trays from strips of several layers of cardboard glued having undergone a certain storage time. Indeed, it is absolutely necessary to heat the material during the shaping of the tray. This results in new costs for heating whereas, due to the time required for said heating, the yield is relatively low. In addition, the production of the trays is made difficult because of the immobility of the different layers of glued cardboard which risk that after forming the packaging, due to a certain elasticity of the material, tends to deform and return to its initial flat position This drawback can only be eliminated by heating the material during the shaping of the tray .

La présente invention a pour but de remédier à ces inconvénients. The present invention aims to remedy these drawbacks.

A cet effet, l'invention concerne un procédé de fabrication d'un emballage du type barquette constitué d'au moins deux couches de carton, de matériaux fibreux, cellulosiques, métalliques, plastiques, caractérisé en ce que, successivement, on prélève d'un dévidoir au moins deux couches de carton en leur impliquant des trajets parallèles, l'un au dessus de l'autre, que l'on enduit de colle par deux postes d'encollage la surface externe de chaque couche de carton, que l'on applique sur cette surface externe enduite de colle un film de revêtement en provenance du dévidoir, qu'ensuite, par l'intermédiaire d'un troisième poste d'encollage, on enduit de colle à prise lente la surface interne de chaque couche de carton, que l'on met en contact, par des moyens appropriés, les deux surfaces internes se faisant face et qu'avant la prise définitive de la colle, on découpe, par un dispositif de découpe, des plats de forme et de dimension correspondant à celles de l'emballage à réaliser et on effectue par une façonneuse le façonnage de l'emballage, le collage définitif des deux couches de carton s'effectuant en fin de la phase de façonnage. To this end, the invention relates to a method of manufacturing a container-type packaging consisting of at least two layers of cardboard, of fibrous, cellulosic, metallic, plastic materials, characterized in that, successively, a dispenser at least two layers of cardboard involving them parallel paths, one above the other, which is coated with glue by two gluing stations on the outer surface of each layer of cardboard, that the a covering film from the dispenser is applied to this external surface coated with glue, then, via a third gluing station, the internal surface of each layer of cardboard is coated with slow-setting glue , which are brought into contact, by appropriate means, the two internal surfaces facing each other and that before the final setting of the adhesive, there are cut, by a cutting device, dishes of shape and dimension corresponding to those from the packaging to carry out and carry out the shaping of the packaging by a shaping machine, the final bonding of the two layers of cardboard being carried out at the end of the shaping phase.

L'invention concerne également un emballage en carton en forme de barquette obtenu par l'application du procédé cidessus.  The invention also relates to a cardboard packaging in the form of a tray obtained by applying the above process.

Les avantages obtenus grâce à cette invention consistent essentiellement en ce que l'on augmente considérablement la cadence de fabrication de l'emballage, tout en assurant le maintien de la forme de la barquette. En effet, au cours du façonnage, les différentes couches de carton peuvent glisser l'une par rapport à l'autre et ne deviennent immobiles qu'en fin de la phase de façonnage. Ainsi, l'emballage peut comporter des arrondis internes et/ou externes dont les rayons de courbure de la couche en carton externe sont différents des rayons de courbure de la couche en carton interne, et on annihile toute tension pouvant provoquer soit une modification de la forme, soit une détérioration par déchirure de l'une ou de l'autre couche de carton de l'emballage. The advantages obtained thanks to this invention consist essentially in that the production rate of the packaging is considerably increased, while maintaining the shape of the tray. Indeed, during shaping, the different layers of cardboard can slide relative to each other and do not become stationary until the end of the shaping phase. Thus, the packaging may include internal and / or external rounding whose radii of curvature of the outer cardboard layer are different from the radii of curvature of the inner cardboard layer, and any tension which may cause either a modification of the form, or a deterioration by tearing of one or the other layer of cardboard packaging.

Figure 2 is an elevational view of the material before cutting and shaping
FIG. 3 is a perspective view of part of a package produced using the process according to
The invention.

On se réfère aux trois figures. We refer to the three figures.

L'installation 1, permettant la réalisation du procédé conforme à l'invention, comporte un dévidoir 2. Celui-ci est pourvu, selon un premier mode de réalisation, de bobines de carton enroulées 3, 4 permettant d'obtenir des couches de carton 5, 6 sous forme de bandes se déplaçant en parallèle l'une au dessus de l'autre ou, selon un autre mode de réalisation, de magasins de feuilles en carton prélevées individuellement. Le nombre de bobines de carton ou de magasins est fonction, d'une part, de l'épaisseur initiale 7 de la couche de carton et, d'autre part, de l'épaisseur finale 8 de l'emballage 9. The installation 1, enabling the process according to the invention to be carried out, comprises a reel 2. This is provided, according to a first embodiment, with coils of cardboard wound 3, 4 making it possible to obtain layers of cardboard 5, 6 in the form of strips moving in parallel one above the other or, according to another embodiment, of stores of cardboard sheets taken individually. The number of cardboard reels or magazines is a function, on the one hand, of the initial thickness 7 of the cardboard layer and, on the other hand, of the final thickness 8 of the packaging 9.

En fonction de l'utilisation finale de l'emballage 9, le dévidoir 2 peut également comporter une bobine de film de revêtement 10 en matériaux fibreux, cellulosiques, métalliques, plastiques servant d'élément de protection interne 11 et une bobine de film de revêtement 12 en matériaux fibreux, cellulosiques, métalliques, plastiques servant d'élément de protection externe 13 de l'emballage 9. Depending on the end use of the packaging 9, the reel 2 may also include a reel of covering film 10 made of fibrous, cellulosic, metallic, plastic materials serving as internal protective element 11 and a reel of covering film 12 made of fibrous, cellulosic, metallic, plastic materials serving as an external protective element 13 of the package 9.

Bien entendu, lorsque les couches de carton 5, 6, sont formées de feuilles en carton, les films de revêtement 10, 12 sont également sous forme de feuilles,
A titre d'exemple non limitatif, on considère que l'emballage 9 est composé d'un film de revêtement interne 10, d'une première couche de carton 5, d'une seconde couche de carton 6 et d'un film de revêtement externe 12.
Of course, when the cardboard layers 5, 6 are formed from cardboard sheets, the covering films 10, 12 are also in the form of sheets,
By way of nonlimiting example, it is considered that the packaging 9 is composed of an internal coating film 10, a first layer of cardboard 5, a second layer of cardboard 6 and a coating film external 12.

On dispose entre la bobine de carton enroulée 3 et la bobine de film de revêtement interne 10, un premier poste d'encollage 16 appliquant sur la surface externe 17 de la couche de carton 5 une fine couche de colle. De même, on prévoit entre la bobine de carton enroulée 4 et la bobine de film de revêtement externe 12, un second poste d'encollage 18 enduisant de colle sa surface externe 19 de la couche de carton 6. Par un moyen approprié 20, 21, on assemble, d'une part, le film de revêtement interne 10 et la couche de carton 5 et, d'autre part, le film de revêtement externe 12 et la couche de carton 6. A first gluing station 16 is applied between the wound cardboard reel 3 and the internal coating film reel 10, applying a thin layer of glue to the external surface 17 of the cardboard layer 5. Likewise, a second gluing station 18 is provided between the wound cardboard reel 4 and the external covering film reel 12, coating its external surface 19 with adhesive on the cardboard layer 6. By suitable means 20, 21 , the internal coating film 10 and the cardboard layer 5 are assembled on the one hand, and the external coating film 12 and the cardboard layer 6 on the other hand.

En aval de ce collage, L'invention prévoit un troisième poste d'encollage 22 permettant d'enduire de colle à prise lente les surfaces internes 23, 24 des couches de carton 5, 6. Ce troisième poste d'encollage 22 est suivi de moyens de rapprochement 25 des deux couches de carton 5, 6 de sorte que l'on met simplement en contact leurs faces internes 23, 24 permettant d'obtenir la paroi future 26 de l'emballage 9. Downstream of this bonding, the invention provides a third gluing station 22 making it possible to coat slow-setting glue on the internal surfaces 23, 24 of the cardboard layers 5, 6. This third gluing station 22 is followed by means 25 for bringing the two layers of cardboard 5, 6 together so that their internal faces 23, 24 are simply brought into contact, making it possible to obtain the future wall 26 of the package 9.

Toutefois, le troisième poste d'encollage 22 comporte une colle dont la prise est retardée et qui peut être relativement fluide.However, the third gluing station 22 includes an adhesive whose setting is delayed and which can be relatively fluid.

Avant la prise définitive de cette colle fluide, l'ensemble constitue une bande 27 que l'on fait passer sous un dispositif de découpe 28 permettant l'obtention de plats 29, 30, 31 dont les dimensions et la forme sont fonction des dimensions et forme finales de l'ensemble de l'emballage 9. Before the definitive setting of this fluid adhesive, the assembly constitutes a strip 27 which is passed under a cutting device 28 making it possible to obtain dishes 29, 30, 31 whose dimensions and shape depend on the dimensions and final shape of the entire package 9.

Alors que le restant 14 de la bande découpée 27 est évacué par un moyen quelconque, les plats 29, 30, 31 sont acheminés vers une façonneuse 32 permettant de conférer aux plats 29, 30, 31 la forme de l'emballage désirée 9. Selon l'invention, ce façonnage est effectué également avant la prise définitive de la colle située entre les faces internes 23, 24 des couches de carton 5, 6. Ainsi, au début de la phase de façonnage, les différentes couches de carton 5, 6 peuvent se déplacer légèrement les unes par rapport aux autres en fonction des rayons de courbure 33, 34, 35, 36 pour se positionner exactement avant le collage définitif, ce qui permet d'éliminer toute tension interne dans la paroi 26 de l'emballage 9. La prise définitive de la colle n'a lieu qu'à la fin de la phase de façonnage.While the remainder 14 of the cut strip 27 is removed by any means, the dishes 29, 30, 31 are conveyed to a shaping machine 32 making it possible to give the dishes 29, 30, 31 the shape of the desired packaging 9. According to the invention, this shaping is also carried out before the final setting of the adhesive located between the internal faces 23, 24 of the layers of cardboard 5, 6. Thus, at the start of the shaping phase, the different layers of cardboard 5, 6 can move slightly relative to each other depending on the radii of curvature 33, 34, 35, 36 to position themselves exactly before the final bonding, which eliminates any internal tension in the wall 26 of the package 9 The final setting of the glue takes place only at the end of the shaping phase.

Sans sortir de l'esprit de l'invention, on peut concevoir que l'emballage 9 ne comporte pas de film externe 12 et/ou interne 10 ou, par contre, est composé de plus de deux couches de carton Dans ce cas, on intercale les couches supplémentaires de carton entre les couches de carton 5, 6. A cet effet, le troisième poste d'encollage est composé d'une batterie de postes de collage, chaque poste de collage étant intercalé entre deux couches de carton et déposant de la colle à prise lente sur les surfaces se faisant face des différentes couches de carton. Without departing from the spirit of the invention, it is conceivable that the packaging 9 does not include an external film 12 and / or an internal film 10 or, on the other hand, is composed of more than two layers of cardboard. interpose the additional layers of cardboard between the layers of cardboard 5, 6. For this purpose, the third gluing station is composed of a battery of gluing stations, each gluing station being sandwiched between two layers of cardboard and depositing slow setting glue on the facing surfaces of the different layers of cardboard.

Bien entendu, 1 invention n'est pas limitée à une couche de carton supplémentaire mais l'emballage 9 peut être constitué d'un nombre de couches de carton quelconque en fonction de la résistance que doit présenter l'emballage 9. Of course, the invention is not limited to an additional layer of cardboard, but the packaging 9 can consist of any number of layers of cardboard, depending on the strength which the packaging 9 must have.

Bien que l'invention ait été décrite à propos d'une forme de réalisation particulière, il est bien entendu qu'elle n'y est nullement limitée et qu'on peut y apporter diverses modifications de formes, de matériaux et de combinaisons de ces divers éléments, sans pour cela s'éloigner du cadre et de l'esprit de l'invention.  Although the invention has been described in connection with a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to the forms, materials and combinations of these. various elements, without departing from the scope and spirit of the invention.
